   a)
    
    the thousands-blocks are required to meet the SPs 6-month projected
forecast
beyond the Pool Start/Allocation Date, orb)
    
    there are technical reasons which justify retaining the thousand-blocks
such as
TNs that are assigned to non-portable services (e.g. packet switched
service), orc)
    
    this is their initial block, or footprint block, even if the thousands-block
is less
than ten percent contaminated2.
  It
is imperative that SPs complete their intraSP ports (ISPs) before the
Block Donation Date. If intraSP ports in the NPAC are not completed and a
donated contaminated block is assigned, there may be service disruptions
including double assignments, for those contaminated TNs.
 On the Appendix 2 Thousands-Block Donation Form there is a field for SPs
to confirm that IntraSP ports have been completed. In completing the Have
All IntraSP Ports Been Completed? field for each block to be donated. SPs
must identify those ports as complete Y or not yet completed N.
 Blocks
may be donated with a N in this field only on or before
the Block Donation Identification Date during initial pool
establishment.
 If
a block is initially donated with N in this field, the Appendix 2 form
must be updated and resubmitted confirming the completion of the ISP(s) on or
before the Block Donation Date. If the N is not updated to a Y indicating
completion of the ISP(s) on or before the Block Donation Date, those donations
will be rejected by the PA and a new Appendix 2 form must be submitted for the
rejected blocks.
 Once
the Block Donation Date has passed, ISP(s) must be completed before
an Appendix 2 form is submitted to the PA.

 It is imperative that SPs complete their intraSP ports(ISPs) before the
Block Donation Date. If ISPs in the NPAC are not completed and a donated contaminated
block is assigned, there may be service disruptions including double assignments, for those
contaminated TNs.
 As noted above, on the Appendix 2 form there is a field for SPs to confirm
that ISPs have been completed. In completing the Have All IntraSP Ports Been
Completed? field for each block to be donated SPs must identify those ports as complete
Y or not yet completed N.
 Blocks may be donated with a N in this field only on or
before the Block Donation Identification Date during initial pool
establishment.
 If
a block is initially donated with N in this field, the Appendix 2
form must be updated and resubmitted confirming the completion of the
ISP(s) on or before the Block Donation Date. If the N is not updated to
a Y indicating completion of the ISP(s) on or before the Block
Donation Date, those donations will be rejected by the PA and a new
Appendix 2 form must be submitted for the rejected blocks.
 Once
the Block Donation Date has passed, ISP(s)) must be completed
before an Appendix 2 form is submitted to the PA.
  
    
    ISP(s) must be completed before an Appendix 2 form is submitted to the PA.
    
    If block donations are submitted using Appendix 2 via PAS, the PA
shall process
the donation within 7 calendar days. If donations are submitted by any other
method, the PA has an additional two business days for processing.
    
    For any donations from a non-pooled NXX, the AOCN is responsible for
entering
its specified routing and rating information for those retained
thousands-blocks.
 
 3
    
    From this data, the identification of thousands-blocks that have
been retained by the Code Holders can be determined. TRA will then initialize the data
for the retained thousands-blocks in BIRRDS resulting in creation of the BCD/NXD
records. Within this process, the LERG Assignee is the CO Code Holder donating the
thousands-blocks. All appropriate data associated with the CO Code Holder will be used
to build the BCD/NXD records for those thousands-blocks retained by the SP. The
Effective Date for all thousands-block(s) retained by the LERG Assignee will be the same as the Block Donation Date.

  
    
    For any subsequent donations of previously retained blocks from a pooled
NXX, the block(s) to be donated must be disconnected by the AOCN in BIRRDS before
donation. An SP should use the Other Information section in Appendix 2 if
block(s) donated have any special status or treatment, e.g., restricted use,
chatline, etc.
  a)
    
    all unavailable TNs within contaminated thousands-b!ock(s)/NXX(s) have been
intra-service provider ported;b)
    
    the associated NPA/NXX is currently available for call routing and is flagged
as
LNP capable in the LERG Routing Guide and the NPAC, and the NPA-NXX
query triggers are applied in all switches and reflected in the appropriate network
databases (e.g., STP routing tables);c)
    
    the NXX-assigned switch is currently LNP-capable and will process terminating
traffic appropriately;d)
    
    interconnection facilities have been established between the NXX-assigned
switch and other interconnecting networks;e)
    
    an SP should use the Other Information section if block(s) donated have any
special status or treatment (e.g., restricted use, chatline, etc.).

 then re-establish the pending LNP port. Another alternative would be to have the
SPs involved attempt to advance the pending LNP port through contact with the NPAC.
  Failure to address all pending ports at the time of thousands-block donation will
result in a rejection of the NPAC activation when that thousands-block is
subsequently allocated to an SP following industry inventory pool establishment. See
Section 8.3.8

Tools
  
    
    A new tool will be provided for each pooling administrator to monitor and track Block
Donation Identification Dates and Block Donation Dates for newly added rate centers in order
to be able to process donations according to the new requirements for conditional acceptance
of donations.
    
    Additional validations will be added to PAS based on the three new fields added to the form,
If Contaminated, How Many TNs Are Not Available for Assignment?, Have All Intra SP Ports
Been Completed? (Y/N) and Has the Block Been Protected from Further Assignment? (Y/N).
 o
    
    Prior to the Block Identification Date,if the block is over 10% contaminated
and/or not protected from further assignment, then PAS will force the PA to reject
the donation.o
    
    After the Block Identification Date,if the block is over 10%
contaminated, and/or the Intra SP ports have not been completed, and/or not
protected from further assignment, then PAS will force the PA to reject the
donation.
 
    
    A new Process Updated Donation work item will be created to notify each pooling
administrator that the SP has resubmitted a conditional donation. The pooling administrator
will process the donation, and if all of the validations are met, the block will be made
available for assignment and will appear in blue on the Blocks Available Report.
    
    A new Reprocess Conditional Donation work item will be created one day after the Block
Donation Date to notify each pooling administrator that the SP has not changed the status of
No in the Have All Intra-SP Ports Been Completed? field. The pooling administrator
will reject the donation, the block will be removed from the Blocks Available Report and the
status of the block will be changed to Retained.
